In a previous post, I talked about Tiny Prims, these were prims that could be shrunk and made into sizes smaller then the original 0.10M object. What if you wanted a sculpt to be smaller? That's even more easy, really it is all you need is Photoshop or if you don't have it or get it gimp (free). There are a couple ways to do this so I just will post links:

Way 1: http://saeluan.net/tutorials/nano-sculpties/
